Another good, cheap, way to water clean is to use a "mister"
spray-bottle like the types used for indoor plant watering. It's real
easy to spray with one hand and to hold open the throttle with the
other while "spritzing".Or, one can adjust the idle screw way out so
only one hand is needed.The nozzle can also be adjusted to exactly
where it works best.
I've always tried to keep the RPM's between 1500-2000, without letting
the engine die. A whole bottle's worth (12oz?) seems to do a real good
job.

Larry,
Your description of the process is quite accurate. When the engine starts
to die down you slow up on the water. Back in the 60's doing a "water
tuneup" on older cars was quite common in the U.S.. My 53 Ford and my 54
Chevy all recieved the treatment. I learned the technique from my father.
He worked on Model T and A Fords growing up, then progressed to an engine
rebuilding business with his brothers and then worked as a Ford dealer
mechanic until 1953. He related tearing down an engine that had a water
injection setup that operated from the engine vacuum. The combustion area
was very clean. J.C. Whitney has sold water injection systems from time to
time. Some pulling tractors use water injection to get more power with out
melting the turbocharger.
